How far is short-term smoothed volume above or below the long-term level in relative terms?

Parameters and precise application
Number of confirmed hourly candles. Warm-up history stays fixed; only this parameter changes.

Explicit formula parameter of the calculation convention described below.
Measurement and diagnosis · no trading direction
Inspect the actual value at each confirmed candle. This analysis produces no buy or sell orders.
Preparing the calculation module. The shared market snapshot is already available.
Calculation and interpretation of the same candle
Positive values show relatively higher short-term volume, not upward price direction.
scalar·(EMA_fast(V)−EMA_slow(V))/EMA_slow(V)
EMA signal and histogram=oscillator−signal; zero denominator unavailable.
Volume increases can occur with rising or falling prices. PVO alone justifies no buy or sell.

The sources support definitions and methodological limits. They do not establish profit for this specific BTCUSDC rule. This analysis is descriptive; parameter trials on the same history are not independent out-of-sample evidence. Parity with a deployed unCoded engine is not claimed.
